Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to a high-resistance and multi-resistance hydraulic hose. Background Art

[0002] Hydraulic hose is a pipe used to transmit liquid or gas, usually made of rubber, plastic or metal materials. It is mainly used in hydraulic systems and can withstand high pressure and high temperature, while being flexible and wear-resistant. Hydraulic hose is commonly used in engineering machinery, automobiles, aerospace and other fields to transmit hydraulic oil, water, air and other media. Its main function is to connect various hydraulic components in the hydraulic system, such as hydraulic pumps, valves, cylinders, etc., to achieve liquid transmission and control. The design and manufacture of hydraulic hoses need to meet strict standards and specifications to ensure their safe and reliable operation.

[0003] Existing hydraulic hoses usually adopt a single-layer structure, which has limited protective performance and is difficult to withstand the influence of harsh environments such as high temperature, high pressure and corrosion. After long-term use, problems such as aging, hardening and cracking are prone to occur, resulting in failure of hydraulic hoses. Hydraulic hoses may be subject to mechanical damage during use, such as extrusion, friction and impact. Hydraulic hoses in the prior art often lack sufficient mechanical strength and are easily affected by these damages, thereby affecting their service life and performance. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a high-resistance and multi-resistance hydraulic hose.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-resistance and multi-resistance hydraulic hose comprises an inner rubber layer, a corrosion-resistant layer is installed inside the inner rubber layer, a plurality of elastic tubes are arranged on the outer wall of the inner rubber layer, the plurality of elastic tubes are connected by a connecting ring, a protective sleeve is installed on the outer wall of the connecting ring and the elastic tube, a steel wire sleeve is installed on the outer wall of the protective sleeve, and an outer layer is installed on the outer wall of the steel wire sleeve.

[0007] Preferably, the outer wall of the outer layer is provided with a plurality of evenly distributed anti-slip grooves.

[0008] Preferably, the elastic tube is an elastic cylindrical structure.

[0009] Preferably, the connecting ring is a circular ring structure.

[0010] Preferably, the wire sleeve is a spring-like structure.

[0011] Preferably, a built-in cavity is provided between the protective sleeve, the elastic tube, the connecting ring and the inner rubber layer.

[0012] The utility model has the following beneficial effects:

[0013] The utility model enhances the resistance of the hydraulic hose to various harsh environments, such as high temperature, high pressure, corrosion, etc., by providing an internal rubber layer, a corrosion-resistant layer, a connecting ring, an elastic tube, a protective sleeve, a wire sleeve and an outer layer. In this way, the service life of the hydraulic hose is significantly extended, the frequency of replacement is reduced, thereby reducing maintenance costs, and the hydraulic hose can better maintain its integrity when facing possible mechanical damage.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A high-resistance and multi-resistance hydraulic hose comprises an inner rubber layer 1, a corrosion-resistant layer 2 is installed inside the inner rubber layer 1, a plurality of elastic tubes 4 are arranged on the outer wall of the inner rubber layer 1, and the elastic tubes 4 are elastic cylindrical structures, the plurality of elastic tubes 4 are connected by a connecting ring 3, and the connecting ring 3 is a circular ring structure, a protective sleeve 5 is installed on the outer wall of the connecting ring 3 and the elastic tube 4, and a built-in cavity is arranged between the protective sleeve 5, the elastic tube 4, the connecting ring 3 and the inner rubber layer 1, a steel wire sleeve 6 is installed on the outer wall of the protective sleeve 5, and the steel wire sleeve 6 is a spring-like structure, an outer surface layer 7 is installed on the outer wall of the steel wire sleeve 6, and a plurality of evenly distributed anti-slip grooves are opened on the outer wall of the outer surface layer 7.

[0021] The use method and advantages of the utility model: When the high-resistance multi-resistance hydraulic hose is used, the working process is as follows:

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this kind of high-resistance and multi-resistance hydraulic hose, the liquid flows through the inner rubber layer 1, and the corrosion-resistant layer 2 has an extremely low friction coefficient and excellent chemical corrosion resistance, which can reduce friction loss, prevent adhesion, and improve the fluidity of the liquid, effectively playing an anti-corrosion effect, and increasing the service life of the internal rubber layer 1. When the liquid has a certain temperature, the heat of the internal rubber layer 1 can be conducted to the protective sleeve 5 through multiple groups of connecting rings 3, and then conducted to the outer layer 7 through the protective sleeve 5, and the heat is discharged through the outer layer 7, which can effectively reduce the temperature of the internal rubber layer 1, prevent it from aging due to temperature accumulation inside when used for a long time, and further increase the service life of the internal rubber layer 1, and prevent The sheath 5 has a certain elasticity, and the elastic tube 4 has a certain flexibility, and can maintain its shape when bent and twisted, and return to its original shape. Therefore, it can prevent excessive twisting and breakage during use, and avoid the hydraulic hose body from breaking and causing liquid leakage. At the same time, when the protective sheath 5 conducts the heat of the internal rubber layer 1, part of the heat will be conducted to the inside of the built-in cavity, so that the pressure inside the built-in cavity increases, which can improve the resistance to external pressure to a certain extent, so that it can better avoid being squeezed by the outside and causing the hydraulic hose body to be squeezed and deformed to break as a whole. Through the overall shape structure of the wire sheath 6, the pressure can be dispersed when it is squeezed by external pressure, reducing the damage caused by pressure concentration.

Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
